****** Page 2 ****** INTRODUCTION The Model 091-150-115 Auto Pump Timer limits the duty cycle oftheAuto Pump to 1 hour “ON” and 1 hour “OFF”. In normal operation the pump runs for less than 1 hour so the timer is not called upon to perform the shutdown function. However, on vehicles with exceptionally large tanks or excessive leaks the pump running cycle is extended. At times, with larger leaks the pump will be forced to run continuously. This creates excessive heat in the pump cylinder and subsequently higher wear on the piston seal. The Pump Timer provides a 1 hour cool down time after 1 hour of operation to materially extend the life ofthe seal. TYPES OF INSTALLATION The motors used in the (2)different AC Auto Pumps are not identical. Therefore they have different starting and running characteristics. The Model 091-9HP contains a permanent split capacitor motor that has an inherently high starting torque. The Model 091-9B-1 utilizes a shaded pole motor with a lower starting torque. The 091-9B-1 thus requires that the cylinder head pressure must be relieved prior to starting. This pressure relieffunction is provided by the Auto Drain and therefore the Auto Drain must be added to the Model 091-9B-1 when the A.C. Auto Pump timer is installed. The 091-9HP will start without the Auto Drain. CAUTION DO NOT OPERATE THE MODEL 091-9B-1 WITH AUTO PUMP TIMER WITHOUT AN AUTO DRAIN INSTALLED

Move the black or brown wire( line wire) from the pressure switch to the first position of the terminal strip (see Figure 1 or 2). Connect a 16AWG wire from the second position of the terminal strip to the open terminal on the pressure switch as seen in Figure 1 or 2. Connect a white or blue wire (neutral wire) to the third position of the terminal strip and the pressure switch on the pump. Check all wiring before proceeding. Close the Pressure Switch assembly.
